I actually have the 2500hd Duramax LTZ (not one of the choices) and with about 2K miles. I drive some dusty roads and like having a camper shell to normally keep things dry and clean, but the bed has so many holes that dust comes into the bed in buckets. My previous 2006 chevy 1500 had a solid bed that I could sleep in the bed, not this truck. They have left big gaps around the tailgate that water and dirt comes and I have tried to add gaskets to seal up gaps but nothing really works. The truck drives ok but the recommended tire pressure at 75psi rear has the back end dancing on every bump. I lower the tire pressure when not hauling, and it helps, but the tire pressure sensor goes off. The seats are much stiffer that my 06 due to the heat/cooling function but I rarely use that function. Lots of AC, DC, USB connections which are handy and the except for the almost useless Navigation system most of the electronics features are good. The lane departure feature is nice as is the backup camera. The body is just not that well built if one uses the truck for other than a city commuter.
Traded in my 2014 LTZ z71 for big brother for reasons: Safety, fuel savings on highway, awesome pulling power, build quality, ergonomics, and great fun driving it. In addition to all these attributes I love buying the last model year cause you know you've gotten everything working properly after it's been out multiple years. I'll be interested in the newer one once everyone else has been used as Guinea pigs working out the glitches of the newer ram air version lol. Overall, this is a high quality badass truck!
I bought a ram 2500 because Chevy/gmc dropped powertrain warranty from 100,000 to 60,000 (to save the consumer money). If General Motors doesn't stand behind there product than neither can I. Mind you this was the first truck I have had that was not a Chevy or gmc.
Even for a work Truck I keep finding great features. Truck runs and rides great. Tows great. (Not going to cry about warranty like somepeople) fwiw only the duramax comes with 100k power train warranty. Truck looks great, runs great. Only negative is it seems to shift a lot. 6-speed over my old 4 speed maybe.
